It consists of a second SCPC channel unit 33 which is encoded, modulated and output.
    Further, reference numeral 40 performs a polling function for checking the state of each base station based on a response message transmitted from the base station after transmitting a control message to each base station through the SCPC channel unit 33, and a specific base station If there is a call request from the base station, the base station determines whether the other base station is in a communication state based on the information obtained in the polling process, and if the communication state is available, allocates available traffic channels of the satellite to both base stations. This is a network control unit that performs system control such as allowing direct communication with each other.
    On the other hand, the network controller 40 extracts packet information from a message applied from the processor 41 and the SCPC channel unit 32, which controls the entire system and in particular, the call processing between the base stations. In addition, a service channel controller (SCC Service Channel Controller) 42 for generating and outputting a message of a time division multiplex (TDM) stream to the SCPC channel unit 33, and the processor 41 and the service channel.

    However, there are not many commands that need to be managed by database using the expensive management system in the commands used by network operators to process information related to system management. In managing the memory more efficiently, it is possible to implement a network management system as a general PC terminal without using expensive equipment.

    FIG. 2 is a block diagram showing an internal configuration of a satellite communication network management system having an index management function for each operator input command group according to an embodiment of the present invention. In FIG. 2, reference numeral 51 denotes an overall system including a base station in which a network manager includes a base station.

The.
    Next, the operation of the device having the above configuration will be described.
    The satellite communication network operation manager monitors the system status including the satellite channel and each base station currently operating through the operator terminal 51 of the network management system 50 and, if necessary, inputs data for system control through contracted commands. When the command is input by the operator, the processor 52 first controls the input command checker 54 to parse and semantic check the command input by the operator. By executing the command, you can check whether the command entered is in error.
    If an error is detected, such as an error check result, the command input by the operator is confirmed as an unusable command in the system, the processor 52 transmits an error message to the operator terminal 51. If not, the full text of the corresponding input command is output to the index manager 61.
    On the other hand, the database management target command registered in the index management target storage 58 is, for example, CRTE create, ADD add, DEL delete, CHAG change, CANL cancel, etc. As the commands related to the system operation, the index management unit 61 may determine whether the command is a database based on whether the operator input command received from the processor 52 is a command registered in the index management target storage unit 58. It is determined whether or not the instruction is a processing target.
    As a result of the determination, when it is determined that the operator input command is not a command to be processed in the database, the index management unit 61 returns the full command to the processor 52 together with the determination result signal. The command returned from the index manager 61 is transmitted to the network controller 40 through the terminal server 55 to execute the command.
    On the other hand, when the operator input command is determined to be a database processing target command, the index management unit 61 reads the index pointer information corresponding to the command from the index pointer information storage unit 60, the index management unit 61 ) Indexes the data storage unit 59 for each index group based on the read index pointer information.
    That is, if it is assumed that the full command command input by the operator is 'CRTE SA GROUP2', for example, the index manager 61 indexes the pointer and the pointer information for the parameter input together with the command and the command from the index pointer information storage 60. The IDX 010 will be read. Subsequently, the index management unit 61 directly accesses the corresponding index from the data storage unit 59 for each index group based on the read index pointer information, and writes 'GROUP2' in the corresponding area. It holds as a system information that the channel 'GROUP2' has been established.
    When the database process is completed, the index management unit 61 then transmits the operator command to the processor 52, the processor 52 transmits the command to the network control unit 40 through the terminal server 55 Sending will execute the command.
    On the other hand, if it is determined that the index area index result, 'GROUP2' already exists in the corresponding index area, the index manager 61 determines that there is an error in the command input by the operator and the processor ( 52) to inform the user of this, in this case, the processor 52 outputs an error occurrence guide message through a monitor (not shown) provided in the operator terminal 51 to execute the command without viewing the user. It provides database functionality so that you can see that there was an error in the statement you entered.
    That is, according to the above embodiment, it is possible to realize a satellite communication network management system configured to provide a database processing function based on information grouped by index for a command input by an operator.
    Meanwhile, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.
    As described above, according to the present invention, the network management system can be implemented as a general PC class terminal without using expensive equipment by managing memory more efficiently in processing a command requiring some database processing.
